Cisco WAN :: High CPU Utilization On Router 2821 With 12.4 (24) T1
Jan 19, 2010I have a Router 2821 with c2800nm-advipservicesk9-mz.124-24.T1.bin and with a Cisco Integrated Service Engine(s) Cisco Unity Express 7.1.1 in slot 1 , this router shows a high cpu utilization.I think is a bug with the IOS , because there is no voicemail configured on the CUE, there is no traffic to the CUE , just traffic from:
- voice calls
- ospf
The ospf is not the cause of the high cpu , because the high cpu utilization appears before I put the ospf proccess on the router.
Cisco WAN :: High CPU Utilization Router 2801?
Apr 12, 2011I have problems with the Router 2801.When i give the command show processes cpu, the command show me that the router is working in 98%.
I have vlans like voice vlan and others, I have one 20 Mb Wan Link and I redirect all traffic from my lan to this link and when i browse in internet or i do downloads the router goes to 98%, when i don't make it the router processes goes down.
I thought be problem with hardware, but i exchange to another router and the same problem happened.Before this situation, I had one link with 12 Mb and nothing happened, when i exchange this to the 20 mb link the problems starting.
Cisco WAN :: High CPU Utilization On 2811 Router
May 9, 2011there is no logging in the access-list (there is only one inbound access list).Using QoS or not, doesn't seem to make a differenceAll route-caching features are ON. (CEF, Flow, Policy, Fast)Yet the minimum CPU utilisation I have seen is 25%/25%... On average it's 40% during the day, but once traffic picks up to around 6000 packets per second, the router is gone...I have a 50/50 Mbps connection, but I can use only 6 for VoIP ?

Cisco WAN :: 7200 Router Facing High CPU Utilization
Dec 6, 2012I have on 7200 series router with NPE-G1 module which is facing high CPU utilization. I have not found any particular process causing this high CPU utilization as it is caused due to interrupts. I have already enabled fast switching by "ip cef" command. Please suggest how to normalize the utilization as it is impacting the network and causing slowness. Please find below the output of show process cpu and also find attached the show tech of the device. Also let me know if any other output is required.

Cisco WAN :: High Memory Utilization In 7206 Router
Jul 29, 2012We have a 7206 router which acts as a MPLS Hub router for around 100+ remote locations. Bandwidh at mpls hub(terminated on this router) is 50 Mbps.
We have noticed that Memory utilization in this router gradually increases and when it reaches 100% this router hangs. It happence in frequesncy of 10 days and we have to restart the router when memory is 100%.
CPU utilization is normal i.e below 20%, WAN bandwidth will never cross 30mbps.
We are running OSPF on this router

Cisco Switching/Routing :: 2821 - Router High CPU Utilization?

View 1 Replies View RelatedCisco WAN :: Routing Loop Due To High Utilization Of Router 3745
Dec 31, 2012I've came across a very odd topology to deal with where everything is connected to everything, without proper utilization of VLANs.
- I've an L3 SW and a 3745 RTR at core
- Both are carrying same subnet to an L2 distribution switch that connects server farm within the same subnet (i.e. 1.1.3.x subnet)
- The L2 switch works as a passive switch, hence another network say, 1.1.2.x has been plugged into it as well.
- This L2 switch extends to other switches without configuration of any VLANs or STP and distributes 1.1.3.x network.
Periodically and unexpectedly, the router starts hanging and utilization goes beyond 80%, and there's nothing at all that is observed in "sh proc cpu" to be eating router resources. Its quite difficult to observe the pattern, as its random.

In LMS the HUM polling has been configured for every 1hr to monitor the cpu and memory utilization.
I have gone through the below cisco document and I have configured all of the snmp-server view commands as illustrated in the below website.[URL] After configuring the same, now we are observing the cpu spike every 4 hrs or i would say 5 hrs... I have checked all the settings of ciscoworks LMS and there is absolutely no other jobs are running in the day time... The spike comes every 4 hrs.

Cisco WAN :: 2811 High Cpu Utilization
Apr 29, 2013I have a 2811 that is really hitting the CPU hard. Nothing shows on CPU processes. It has an IPsec VPN tunnel back to HQ which also has a 2811 that terminates the VPN. The HQ has 2-3 IPsec tunnels to other remote sites. The CPU at the HQ avg 50% utilization during business hrs, peaks at about 80%. The remote one is very high 95% peaks, avg 80%-95% during business hours with bandwidth utilization of only 10-20Mbps. I read somewhere that its possible that fragmentation could be causing this. My question is, if I set the MTU to 1450 on the remote, I am guessing I will need to do all the other routers as well, the HQ and other remote sites? Siince they use the same outside interface to my HQ, is that correct?

View 1 Replies View RelatedCisco :: 7613 Having Frequent High CPU Utilization?
Apr 25, 2012I have Cisco 7613 on my edge(MPLS Backbone). CPU utilization is shooting to 100% at frequent intervals. When I tell vendors managing device they tell that it is happening due to one of my server(connected on Fast ethernet port of 100Mbps) generating heavy traffic. My questions are:
1. Can a router of 720Gbps capability be choked due to traffic generated by 100Mbps link?
2. Interrupt CPU process utilization is well below 10% at the said time. BGP router process consumes most of the CPU. Does this means that server in question is generating too many routing updates?
3. Is there any way that I can limit routing updates on a particular link?
4. how to check which link is causing more CPU utilization.

Cisco Firewall :: High CPU Utilization On ASA 5550?
Mar 10, 2013I have Active Standby ASA5550 setup with VPN premium license. A few days back we had a requirement of SSL VPN connection for and we got a temporary from Cisco for same, this license expired and the ASA reverted to it's original license. 3 4 days after this we saw a sudden increase in CPU utilization (upto 90% + -5%) on the ASA during production hours but were not able to figure out the reason, in order to restore the services we failovered the firewall to secondary and everything worked fine. We were suspecting one of the following but there were no logs for any of this
1. The ASA hardware was haivng problem
2. Some client was doing a DoS attack to bring down the ASA (no logs for this as well).
We took a downtime to look further by failovering the ASA back to primary and it worked fine without any issues ruling out the 1st option. We also came across a licesing doc [URL]
Downgrading any license (for example, going from 10 contexts to 2 contexts).
# Note If a temporary license expires, and the permanent license is a downgrade, then you do not need to immediately reload the security appliance; the next time you reload, the permanent license is restored.
As per this doc, sooner or later a restart was required on the ASA. We restarted secondary ASA and everthing was fine but when we restarted the primary ASA by swtiching over to secondary some of the server (not all) in the DMZ stopped working (even ICMP unreachable) and only came back to normal when the primary ASA was restored and working fine (with failover).
The reboot was done by shuting down the physical link between the Core switch and ASA inside individually.
I am not sure what could be the issue that the servers in the DMZ wen unreachable.
